Process of rendering textile pneumatic tires puncture-proof



M beowzo UNITED v STATES LEE HOFFMAN STODDE PROCESS OF RENDERING TEXTILESPECIFICATION forming part of Letters Patent No. 586,926,

Application filed October 28, 1896.

To all 2072 0722, it m y nouoern:

Be it known that I, LEE HOFFMAN STODDER, a. citizen of the UnitedStates, residing at New York, in the county of New York and State of XewYork, have invented certain new and useful Improvements in the Processof Rendering Textile Pneumatic Tires Puncture- Proof, of which thefollowingis a speeifi cation.

This invention relates to improvements in th 0 process of rendering p11en matio tires p u noture-proof, the process consisting in treating thefabric or material the tire to render it puncture-moot and,incidentally, impervious to moisture.

To accomplish the objects of my invention I ii rst make a solution offive gallons of Water 1.116. IWO lJOlliH'lR fit nnel y 1 [5: -,,I,. thelime istliorrm -lil mix-ml 1n the water I immerse the tire materialtherein and let it remain in the alkaline solution for five or morehours, when the material is removed and thoroughly dried eitherbyatmospherie exposure or by otliersuitahle process.

The quantity of lime solution above named is that intended for thetreatmentof about fiftyyarlils of the tire material. This alkalinetreatment prepares the material for the subsequent indurating sandaraccoating. The alkaline solution thoroughly saturates the iahrie and iillsthe meshes thereof, making it less liable to puncture and presenting aproper which forms a part of PATENT Grates.
